The association between diet and health has been identified, and a healthy diet can help prevent various cardiovascular diseases (CVD). Dietary behaviors and dietary patterns are changing, especially in developing countries; with the ever-increasing amount of processed food and changing lifestyles, people eat more foods rich in energy, fat, free sugars, and salt, but not enough in fruits, vegetables, and other dietary fibers. CVD, including coronary heart disease, heart failure, stroke, and hypertension, are the leading cause of mortality worldwide. Poor dietary behaviors and patterns are risk factors for the continuing increase of CVD incidence, accounting for more than 11 million deaths.
